Can I use my self-hosted ntfy?

Yes, if it is reachable over public HTTPS: FishOut checks at send time that the hostname resolves only to public addresses. Use ?auth= on the topic URL for a protected topic.

Will it push every comment that mentions us?

Only those that clear your floor, and comments currently push without a title of their own. Stories and Ask HN posts carry their titles, like the sample here.

How quickly does the push arrive?

Hacker News is checked hourly on every plan, and every 15 minutes for Fast keywords on a paid plan. The push goes as soon as the post is read.

What does tapping the notification do?

It opens the mention in FishOut, with a reply drafted in your Voice. The second action opens the HN thread itself.

Hacker News push alerts, via ntfy

People who self-host ntfy usually already read Hacker News, and the do-it-yourself version is an hnrss feed piped through an RSS-to-ntfy script. FishOut replaces the feed and the script, and adds the part they cannot: an Ask HN that wants an answer now pushes at high priority, everything else at default.

[03] KEYWORDS THAT WORK HERE/ HACKER NEWS

For Hacker News, into ntfy

More keyword shapes are on monitoring Hacker News.

Ask HN phrasing: “recommend”, “what do you use for”

These are the posts that earn Reply now, which is what ntfy turns into a high-priority push.

Leave broad brand terms off this channel

Send them to a chat channel instead. ntfy is for the few posts with a deadline.

A floor of 90

At 90 the push is almost always a post you would act on tonight, and the high-priority ones are the ones that cannot wait until morning.

[04] SET IT UP/ 4 STEPS

Four steps, about five minutes

Hacker News into ntfy, start to finish.

1
Pick a topic nobody will guess
Walkthrough on the ntfy guide.
2
Paste it under Settings → Notifications → ntfy
Then send a test.
3
Add Hacker News keywords under Keywords
Start with: Ask HN phrasing: “recommend”, “what do you use for”.
4
Floor 90, mention.scored
Batching stays on.

Priority is set for you

ntfy priority runs from 1 to 5. FishOut sends 4 (high: long vibration, pop-over) when the Reply call is Reply now, and 3 otherwise, so the buzz itself tells you which kind of post it is.

[05] A BUSY DAY/ DIGEST

When Hacker News gets loud

On ntfy.sh’s free tier, 250 messages a day is the budget for the whole topic. A launch day without batching can spend a fifth of it in an hour; with it, one push opens the window and one push closes it.

[06] THE RECIPE YOU WOULD OTHERWISE BUILD/ DIY

hnrss keyword feed + an RSS-to-ntfy script

hnrss.org serves a feed of new HN posts matching a query, titles only by default; a self-hosted tool such as vigilant polls it and pushes each new entry to ntfy.
